Charley Boorman's Extreme Frontiers

California (3x4)

:

Charley sets off on the final leg of his journey, scaling a cliff in Colorado before visiting a soda ash mine in Wyoming. He then heads to the Bonneville Salt Flats in Utah and joins Erin Hunter and Andy Sills in an attempt to set a world speed record for three people on one motorbike, and then rides through a surprisingly wet Death Valley in California. Charley eventually reaches the Pacific coast, where a large convoy of like-minded bikers join him on the ride into his final destination of Los Angeles
